MAP.

SPECIFICATION YTo Vcir/ZZ whom t may concern: I

Be it known that I, EMIL HEUBACH, a citiful Improvements in Maps, of which the following is a full, clear, and exact specification. My invention has for its object the production ofa map designed principally for large cities which shall be so constructed as to enable a stranger to readily locate any particu-V lar place or object, to calculate distances, and

to determine the relative location of the different street-car lines, both surface and elevated, together with all stations and stoppingpoints of the elevated railroads.` l

In maps of large cities as heretofore constructed the blocks have been divided into squares or sections and the spaces intervening between these squares or sections represent the streets and boulevards. This method employed the use of so many lines upon the map that it was impossible to distinctly illustrate all or in some instances any of the streetcar lines running upon a particular street or to show the connection made by one car-line with another. By my construction I am enabled to show distinctly all of the car-lines running upon any given street and by means of my index to enable a person to locate any place in the city and to inform himself what car to take in traveling from one place to another.

In the drawings led herewith Ihave shown, for illustration, a portion of the city of Chicago, together with an index or guide to be used in connection with the map and in explanation thereof.

Other novel features of my map will be more particularly described in the specification and pointed out in the claims.

In carrying out my invention I provide a map which I g have illustrated in preferred form in the accompanying drawings,'in which- Figure lY is aportion ofa map illustrating.

forming part of Letters Patent No. 54,450, dated March 1904.

Application filed March 5, 192.

serial No. 96,862. (No niodei.)

this kind, by having squares and sections representing the blocks into which the city is divided, leaving the intervening spaces to represent the streets and boulevards, I have drawn what I term imaginary center ylines--that is, lines which represent the intersection of the streetsa'nd within these intersections would be'the blocks,were it necessary to show them. i These center lines are here represented by light dotted lines throughout vthe entire map` By this methodI am enabled to show every block inthe city and yet do away With mre' than half the lines used in other maps, and therefore have suificient space to place the names of all the streets, show all the streetcar lines, railroads, and elevated railways, together with their stations, thus `enabling one to locate the elevatedy station most conveniently reached from any, particular place. It

is therefore easy to trace the route traversed' by any particular street-car line, as by my..

method of constructing the map I illustrate each individual line throughout its entire length, and where a number of different carlines traverse the same street, whether on the same tracks or not, each trackis indicated by a separate line,V which lines are parallel for the respective distances said car-lines traverse the same street.

In my index shownin Fig. 2 it will be observed that I have divided the city into the north and northwest section, the west and southwest section, and the south and southwest section with reference to lines of transportation to-enable a person to more readily locate any given car-line. I khave classified the different car-lines under the headings Lines, Start from, f Run in the following streets# End at. At the left of each line I have placed a number or letter, which number will be found ,at intervals upon the map upon the particular line designated. Under the heading Abbreviation and remarks V I have explained abbreviations for words frequently used upon the-map, also references Other information regarding v above Will serve to explain my map.

IOO

By referring to the index as shown in Fig. 2 the number of any car-line wanted may be readily ascertained, or if the number is known by referring to said index the name of the line may be readily ascertained and its entire route traced on the map. When it is desired to know the route of any particular ear-line, its proper designation is found, and then by referring to the index containing this letter or ligure the entire route will be found fully explained. For illustration, the Wentworth avenue car is indicated by e. Referring to the index, it will be seen that this car starts from Washington and Clark streets, runs south in South Clark street, Twenty-second street, Wentworth avenue, Seventy ninth street, and ends at Auburn Park. By tracing the line designated e on the map the entire route of the Wentworth avenue car could be followed.

I do not desire to limit myself to the precise construction and arrangement herein shown of either the index or map, as the details thereof might be changed without departing from the spirit of my invention, which consists, essentially, in laying out the foundation of the map with lines representing the center of the street instead of dividing the city into squares or sections to illustrate the blocks.

I claiml. The herein-described map, having as the foundation thereof dotted lines representing clear streets, each of said streets represented by a single dotted line, said map having different characters of railroads represented by characteristically-different lines, and means for indicating each railroadthroughout independently of every other railroad, said means indicating each railroad in the streets traversed by more than one railroad, substantially as described.

2. A map having as the foundation thereof dotted lines representing clear streets, each of said streets represented by a single dotted line said map having different characters of railroads represented by characteristically-different lines and means for indicating each railroad throughout independently of every other railroad, said means indicating each railroad in the streets traversed by more than one railroad, and means consisting of individual reference characters for the several railroads distributed at intervals throughout the length of the same, and an index-section explanatory of the route and character of each individual line and each having a symbol analogous to the reference character to which it relates, substantially as described.
